'lO` ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN S. EVERITT, of the city of Oshkosh, in `the county of Winnebago, and State of Wisconsin, have invented a new and improved Method of Adjusting the Gearing ofthe Climax Horse-lon'er; and I do hereby declarefthat the following is a full and exact `description thereof, reference being had to the accompanying` drawings, and to the' letters of reference marked thereon.

The nature of my invention consists in placing au adjustable clutch upon the shafts carrying the masterpinions of the horse-power, in'such a manner that the said pinions Ycan be slightly rotated and adjusted upon their shafts, so that all parts of the gearing will have theirprcper relative positions, and the strain upon the teeth of all the gears will be equalized.

To enable others skilled in the art to make and use my invention, will proceed to describe its constrnction and operation.

Figure l is a. top view of the horse-power, in which m is the master-wheel,up the 'mast-er-pinions, n n the centre bevel-gears, o the centre pinion, s the shaft, from which the power is taken oil', andt tthe adjnslable clutches, which are th'e subject of this application. I

Figure 2 is a view ofthe clutch `and its appendages on alarge'scale.

P is the pinion, which is in one piece with the part A of the clutch, and is loose on the shaft, being held `in place by shoulders thereon, and kept from rota-ting on the shaft by the other part of the clutch, B. The

part B can move endwirse onv the shaft, but is kept from rotating thereon by the'splinc c, and is secured in place by the set-screw d.. The faces ofthe parts A and B, where they come in contact, are not parallel with the shaft, but are in the form of a. spiral inclined plane,lso that as the part B is moved back and forth, the pini'on will be turned one way or the other on the shaft.

When the horse-power is set up, the master-pinions are adjusted by means ofthe clutches, so that the strain on the teeth of all the gearing will be equalized. l

What I claim as my invention, and desire to'securc by Letters Patent, is

The clutch, with inclined faces, for the purpose of adjusting the gearing of the horse-power as set forth.
